A feed apparatus for isolating and feeding spirals ( 3 ) or the like to a binding apparatus has an isolating roll ( 12 ) comprising depressions ( 19 ), which are distributed over the circumferential surface ( 11 ) thereof and are parallel to the axis, for receiving in each case a spiral ( 3 ), which circumferential surface ( 11 ) is moved under a scraper ( 20 ) which comprises a chain ( 25 ) which is moved in the opposite direction over two rollers ( 21, 22 ) arranged vertically one on top of the other and which carries outward-projecting scraping fingers ( 27 ) which are in the form of bundles of resilient bristles. From the circumferential surface ( 11 ), the spirals ( 3 ) pass via a baffle plate ( 40 ) onto a conveyor ( 30 ) having drivers ( 37 ) which transport them to a slot ( 43 ), where they are delivered to the binding apparatus. If no spiral ( 3 ) was picked up by the depression ( 19 ) of the isolating roll ( 12 ) and further transported to the conveyor ( 30 ), the baffle plate ( 40 ) is advanced in the conveying direction for avoiding a failure.
